A simple and cost effective method was reported for the synthesis of β-SiC nanoparticles with differernt morphologies using Taixi coal as carbon source and Fe (NO3)3·9H2O, Co (NO3)2·6H2O and NiCO3·2Ni (OH)2·4H2O as additives, respectively. The structures and morphologies were characterized by XRD, FTIR, BET and SEM. The results show that SiC nanoparticles with lamellar structures were successfully synthesized at 1450 °C with NiCO3·2Ni (OH)2·4H2O as an additive which are very scarce to our knowledge. whats more, the formation mechanism of lamellar structures SiC nanoparticles were also discussed.

This paper introduces a cost-effective method for the fabrication of stretchable circuits on polydimethylsiloxane (PDMS) using inkjet printing of silver nanoparticle ink. The fabrication method, presented here, allows for the development of fully stretchable and wearable sensors. Inkjet-printed sinusoidal and horseshoe patterns are experimentally characterized in terms of the effect of their geometry on stretchability, while maintaining adequate electrical conductivity. The optimal fabricated circuit, with a horseshoe pattern at an angle of 45°, is capable of undergoing an axial stretch up to a strain of 25% with a resistance under 800 Ω. The conductivity of the circuit is fully reversible once it is returned to its pre-stretching state. The circuit could also undergo up to 3000 stretching cycles without exhibiting a significant change in its conductivity. In addition, the successful development of a novel inkjet-printed fully stretchable and wearable version of the conventional pulse oximeter is demonstrated. Finally, the resulting sensor is evaluated in comparison to its commercially available counterpart.

Preparation Conditions

Ga2O3 nanowires were prepared by vapor-solid process in atmosphere, using commercial Ga ingot and Ga2O3 powder or Al2O3 powder as the starting materials. The influence of preparation conditions such as temperature and starting material on the products was studied. The composition and morphology of the products were characterized by XRD, SEM/EDX, TEM, and HRTEM. The formation mechanism of the products was proposed.
